I know what you wrote. My remark was intended as a swipe at the marginal integrity produced by the Cerec InLab machines (I guess you’re alright with letting the luting medium fill in any marginal discrepanicies?). I spoke with an Ivoclar representative about this situation. I was told that each and every mill B&D puts in the market would have to be individually “verified”. Ivocalr evidently made Diadem go through this process with their mills, and I was told it took 6 months and loads of paperwork. However, the Cerec InLab mills are “verified” en masse. I recognize this may have to do with the milling strategies, however it smells more like it has to with money. Its not surprising that Ivoclar has chosen to cut deals with the big boys – Sirona, NobelBiocare, Straumann, and Diadem. However, your suggestion that the milling stategies used by these major players can’t be replicated just doesn’t wash with me.

I said MATERIAL integrity.
Margins are one thing and I am sure that the Origin machine does just fine with them.
Material integrity is something entirely different. If a machine is stressing the material during the milling process to the point where its flexural strength is compromised, your perfect margins won’t mean much. Of course no one would ever blame the machine for a failure. It would always fall on the material.

Excellent point. This was a one time deal okayed in advance by the doctor. What’s funny about your comment is questioning the marginal integrity of the material as milled by the Origin machine versus having no marginal integrity whatsoever as milled by the Cerec InLab… As for the “approval process” – I’m willing to bet it has a whole lot more to do with the politics of money than actual results. A large company like Ivoclar is not going to approve B&D because to do so would be to virtually spit in the face of Sirona, Straumann and NobelBiocare. So BillBill, rest assured I won’t be doing anymore such cases – but not because it doesn’t work.

As an non-approved milling machine, I would wonder what effect it is having on the material integrity of IPS e.max. Ivoclar has a very strict validation process and thus far, Origin has not been approved for milling IPS e.max. A crown might look great, but does Origin have any information on the flexural strength after milling on THEIR machine?
Strength values can vary based on the trauma (or lack thereof) that a restorative material goes through during the milling process and until Ivoclar Vivadent OK’s Origin, there is no telling what is happening with that product.
